Set Out Surveys for Accurate Construction

Accurate, on-site layout is the foundation of every successful construction project. At MCS Surveyors, our Building Set Out Surveys ensure your structure is positioned correctly on your land in accordance with approved plans, helping you stay compliant and avoid costly errors.

Building set out surveys involve far more than marking points on a block. They require an understanding of the approved development plans, current land title boundaries, and any local council regulations that may impact your build. Our role is to bridge the gap between design and construction, providing precise references for builders to work from with confidence.

We support residential, commercial, and civil contractors by providing:

Site-ready survey marks that correspond exactly to your plans
Survey reports that confirm compliance with council permit conditions
Ongoing consultation if changes to the design occur during construction

With the complexity of modern construction and the growing importance of accuracy, investing in a professional set out survey is a safeguard against structural misalignment, legal setbacks, or costly rebuilds.

What Is a Building Set Out Survey?

A building set out survey is the process of transferring your approved building design from paper (or digital plans) directly onto the physical site using precise survey instruments. This is done by a licensed surveyor who marks key reference points and outlines on the ground, showing exactly where structural elements like walls, columns, and footings will be constructed.

These marks serve as the foundation for the entire build, ensuring that every element is correctly placed within your property boundaries and according to council-approved development plans. The surveyor references control points, boundaries, and design coordinates to calculate the exact positions required on site.

Commonly marked features in a building set out survey include:

External walls and slab edges
Gridlines for structural frames
Service entry points (e.g. plumbing, electrical)
Setbacks from boundaries
Finished floor levels

Without an accurate set out, builders may unknowingly begin work in the wrong location; leading to boundary encroachments, non-compliance with permits, or misaligned structures that are costly and time-consuming to fix.

Why Building Set Out Surveys Matter

A building set out survey is essential to the integrity and legality of any construction project. It ensures that construction takes place exactly where it should; avoiding encroachment onto neighbouring properties, non-compliance with development approvals, or costly structural corrections down the line.

Here’s why a professional set out survey is so important:

Boundary Compliance

The survey confirms your build stays within title boundaries and setback requirements as specified by local planning rules.

Permit Accuracy

It ensures your structure aligns with what’s been approved by council and any building permits issued, which helps avoid potential stop-work notices.

Construction Efficiency

Builders and subcontractors can use physical site markers and accompanying set out drawings as reliable reference points, which speeds up site preparation and reduces mistakes.

Foundation Precision

Accurate layout of slab edges, footings, and services reduces the risk of structural misalignment, which can be expensive and difficult to rectify after concrete is poured.

Height and Level Checks

Set outs can also include finished floor levels and vertical benchmarks to ensure the right elevations are achieved throughout the build.

Whether it’s a single dwelling or a large commercial development, set out surveys give all parties (including builders, engineers, and certifiers) the confidence to proceed without second-guessing critical measurements.

Suitable for All Types of Construction

At MCS Surveyors, we provide building set out surveys for a wide range of residential, commercial, and civil construction projects. No matter the scale or complexity, our team ensures your design is accurately translated onto the site so construction can begin with clarity and confidence.

We support projects including:

New home builds and extensions
From single dwellings to duplexes, we mark out walls, slabs, garages, and service locations in full alignment with architectural drawings.
Multi-residential and commercial buildings
We set out gridlines, lift shafts, stair cores, fire exits, and other structural elements across multiple storeys.
Infrastructure and civil works
For roads, bridges, and drainage systems, we provide control points and alignments to guide earthworks and construction crews.
Swimming pools and outdoor structures
We mark out pools, patios, and retaining walls to ensure compliance with design and boundary conditions.
Kiosk and internal fit-outs
In retail environments, we assist with the layout of shopfronts, kiosks, and internal lease areas.
Fencing and boundary works
For new fences or boundary adjustments, we ensure all structures are correctly positioned according to survey plans and title boundaries.
Plant, lighting, and equipment layout
In industrial settings, we can assist in positioning equipment pads, light poles, and mechanical systems.

Each project has its own set of challenges; whether it’s limited space, tight tolerances, or coordination with other trades. That’s why we tailor our service to the specific needs of your build and communicate clearly with site teams to minimise disruption.

Our Process

At MCS Surveyors, we follow a structured and transparent process to ensure every building set out survey is completed accurately, efficiently, and in full alignment with your project needs.

Initial Consultation

We begin by discussing your construction plans, site conditions, and permit requirements. This helps us define the scope of the survey before arriving on site and identify any special considerations; such as tight setbacks, level constraints, or staging requirements.

Data Preparation

Using the architectural or engineering plans you provide (typically in CAD or PDF format), our team converts design points and levels into set out coordinates. These are matched to real-world positions using site control and property boundary data, allowing for highly precise translation from plans to ground.

Site Survey and Marking

Our qualified surveyors attend site with high-precision total stations and GNSS equipment to physically mark out all key reference points. We use durable survey pegs, nails, paint marks, or custom markers based on the nature of the site and the builder’s preferences.

We can mark:

Gridlines and wall alignments
Corners and slab edges
Footing centres and service entries
Floor levels and height benchmarks

The number of marks placed is based on your construction sequence and agreed scope of work.

Plan Preparation

Once the fieldwork is complete, we generate clear set out plans using industry-standard drafting software like AutoCAD. These plans include reference coordinates, dimensions, offsets from boundaries, and any relevant levels. Plans are delivered in PDF and DWG formats for easy integration with your builder’s documentation.

Quality Assurance

All set out data and plans go through internal review and checks to confirm alignment with your design files, title boundaries, and permit requirements. This ensures you receive a survey product that is accurate, consistent, and construction-ready.
